Surgical sealing element holder for holding a surgical sealing element and surgical sealing system

Abstract

In order to improve a surgical sealing element holder for holding a surgical sealing element of a surgical sealing system comprising a trocar with a trocar sleeve, the sealing element having an insertion opening which can be widened, such that a sealing element of the sealing system can be replaced in a simple and reliable manner and it is ensured that sealing in relation to a channel of the trocar sleeve is perfect at all times it is suggested that a holder sealing element be provided for sealing the sealing element holder with respect to an inner wall surface of the trocar sleeve. In addition, an improved surgical sealing system is suggested.

1. A surgical sealing element holder for holding a surgical sealing element of a surgical sealing system comprising a trocar with a trocar sleeve, said sealing element having an insertion opening adapted to be widened, the surgical sealing element holder comprising:
 a holder sealing element for sealing the surgical sealing element holder with respect to an inner sealing surface of the trocar sleeve, wherein: 
 the holder sealing element is designed in the form of a flange projecting from the surgical sealing element holder in a radial direction, 
 the holder sealing element is monolithically formed with the surgical sealing element holder, 
 and the flange is inclined at an angle of inclination of between 1-15 degrees in a distal direction with respect to a plane extending transversely to a longitudinal axis of the surgical sealing element holder. 
 
     
     
       2. Surgical sealing element holder as defined in  claim 1 , wherein the surgical sealing element holder is designed for a detachable connection to the trocar sleeve. 
     
     
       3. Surgical sealing element holder as defined in  claim 1 , wherein the holder sealing element is deformable elastically at least in sections. 
     
     
       4. Surgical sealing element holder as defined in  claim 1 , wherein the holder sealing element has an additional seal. 
     
     
       5. Surgical sealing element holder as defined in  claim 4 , wherein the additional seal is produced from an elastomer. 
     
     
       6. Surgical sealing system, comprising:
 a trocar with a trocar sleeve, 
 a surgical sealing element having an insertion opening adapted to be widened, and 
 a surgical sealing element holder for holding the surgical sealing element, 
 the surgical sealing element holder having a resilient holder sealing element for sealing the surgical sealing element holder with respect to an inner sealing surface of the trocar sleeve, the holder sealing element being adapted to be pressed against the inner sealing surface of the trocar sleeve with a pretensioning force; 
 wherein:
 the holder sealing element abuts on an annular surface of the trocar sleeve, and 
 the annular surface faces toward a proximal end of the surgical sealing system in a position of use, and 
 the annular surface has an additional seal. 
 
 
     
     
       7. Surgical sealing system as defined in  claim 6 , wherein the holder sealing element is deformable elastically at least in sections. 
     
     
       8. Surgical sealing system as defined in  claim 6 , wherein the surgical sealing element holder is adapted to be connected detachably to the trocar sleeve. 
     
     
       9. Surgical sealing system as defined in  claim 6 , wherein the trocar sleeve has a sealing element holder receptacle for insertion of the surgical sealing element holder. 
     
     
       10. Surgical sealing system as defined in  claim 6 , wherein the additional seal is produced from an elastomer. 
     
     
       11. Surgical sealing system as defined in  claim 6 , wherein the annular surface is defined by a one-step narrowing of an inner diameter of the trocar sleeve. 
     
     
       12. Surgical sealing system as defined in  claim 6 , wherein the surgical sealing element seals the insertion opening during insertion of a surgical instrument. 
     
     
       13. Surgical sealing system as defined in  claim 6 , further comprising a surgical protection device for the surgical sealing element, said protection device comprising a base member adapted to be arranged on the trocar or on a part of the trocar, the protection device being closed in a ring shape or closed approximately in a ring shape and having an opening and several protection elements arranged in circumferential direction and pointing parallel to or towards a longitudinal axis of the protection device, said protection elements having free ends pointing approximately in a distal direction, wherein at least some of the protection elements have at least one retaining element on an outer side at their free ends or in an area of their free ends for engagement with the surgical sealing element. 
     
     
       14. Surgical sealing system as defined in  claim 13 , wherein the at least one retaining element is designed in the form of a retaining projection protruding from the protection elements. 
     
     
       15. Surgical sealing system as defined in  claim 13 , wherein at least some of the retaining elements project at right angles or approximately at right angles from the protection elements or point away from the protection elements at an angle with respect to an extension of the protection elements in the area of their free ends. 
     
     
       16. Surgical sealing element holder as defined in  claim 1 , wherein the inner sealing surface forms an inner wall section of the trocar sleeve. 
     
     
       17. Surgical sealing system as defined in  claim 6 , wherein the inner sealing surface forms an inner wall section of the trocar sleeve. 
     
     
       18. Surgical sealing system as defined in  claim 6 , wherein the holder sealing element is designed in the form of a flange projecting outward from the surgical sealing element holder in a radial direction. 
     
     
       19. Surgical sealing system as defined in  claim 18 , wherein the flange is inclined at an angle of inclination of between 1-15 degrees in a distal direction with respect to a plane extending transversely to a longitudinal axis of the surgical sealing element holder.
